运行后点击按钮：
然后重启后点击按钮：
发现没？开机自动启动后
Environment.CurrentDirectory 发生了变更，
这样在在我们程序中原本如果使用相对路径进行处理的，就找不见相应的文件了，
怎么处理？
方法1：
在程序初始化的时候改变下当前路径
public Form1() { InitializeComponent(); Environment.CurrentDirectory = AppDomain.CurrentDomain.BaseDirectory; }
方法2：添加环境变量 , 计算行--属性--高级系统设置--环境变量--系统变量里面设置.
static void Main(string[] args) { Console.WriteLine("更多精品搜索公众号：" + "dotnet编程大全"); Console.WriteLine("C#技术交流群："+"添加小编微信" + "zls20210502"); Console.WriteLine("切记备注：加群"); Console.ReadKey(); }
